Multigauge V9
Pictures of the current/latest version V9:
This Multigauge is specifically designed for the Yamaha FZ1 Gen1 dashboard
(up to modell '05, in Europe: Fazer FZS1000) to replaces the stock fuel gauge. It shows various
informations about the status of the motorbike and provides additional functionality.
The core is a digital processor and a liquid crystal display.
This is no official accessory and has no ties to Yamaha.
Data and Functions
A brief overview and summary about the displayed data and implemented functions:
Gear Indicator: The currently selected drive gear, including Neutral. Calculated from
rpm and speedo informations.
Fuel: The fuel content in the tank. Corrections are applied to reach maximal accuracy.
The tank geometrie is modeled by a 10 point interpolation, fully customizable. The "real life" fuel capacity is
19 liter due to the remaining air buffer (Fazer datasheet: 21 liter).
Water temperature: The orignal sensor signal is used, located in the thermostat housing.
Ambient temperature: Provided by an extra sensor that comes with the gauge.
Battery voltage: The current supply voltage inside the dashboard. Unfortunately this reading is significantly
offset from the battery terminals due to the poor original cable harness.
Speed and correction: The current velocity based on the speedometer sensor. Optionally corrected
by an adjustable static factor and a wheel-spin compensation. Readout in Km/h or MPH.
Speedometer correction: Correction for the original analog (needle) speedometer and odometer.
Applying a correction factor to the speed signal and feeding it back into the dashboard. Mainly used
in case of changed sprocket ratios.
Acceleration: A timer starting automatically at first move and counting up until a certain speed
or distance is reached (e.g. 1/4 mile).
Stop watch: Start/stop or laptime for use on race tracks. Optionally controlled by an extra
button at the handlebar.
Gear shift indicator: The warning LED starts flashing beyond a certain rpm value.
The limit can be set individually for each gear.
GPS Data: Showing GPS-Data from an additional, external GPS receiver (speed, height, course,
time, etc. ). The HW and SW is prepared to read and decode NMEA-data. The GPS receiver is not part
of the package.
Fuel Economy: Showing the current fuel consumption as miles-per-gallon or liter-per-100km.
This function requires to route an additional cable and tapping the fuel pump.
Views: The displayed informations are grouped into several windows. The user can choose his preferred
design and arangement from a predefined catalogue.
Menu: A settings menu is integrated to change units and adjust or check sensors.
FZS600 models are supported, but with restrictions.

Functional expectations and limitations
The gear calculation requires a speedo signal. There will be no gear reading at standstill.
The Multigauge's accuracy highly relies on the quality of the sensor data available within the dashboard.
Therefore a few limitations have to be noted.
The tank sensor was never designed for high accuracy. Also the nature of this measurement (permanent sloshing)
is challening. Hence there might be situations where the appplied computational "tricks" come to their limit.
The "battery voltage" is measured inside the dashboard, not directly at the battery terminals. The poorly designed
original Yamaha cable harness sits in between and causes a significant voltage drop. Even worse, this
offset is floating and therefore can't be accounted for.
The water temperature sensor is located near to the thermostat. Thus the temperature is a mix between inner and outer
cooling loop. Especially in cold ambient conditions the reading might stay unexpectedly low.
Tapping the sensor's electronics comes with the (intended) side-effect of lowering the kick-in temperature of the fan
by about 5°K (105°C -> 100°C).

Ordering, Prizing and Shipping
Ordering and prizing only on individual request per email.
A few informations and selections have to be considered upfront:
- The frontplate is pure black anodized aluminium without any decoration. No deviations possible.
- The default model assumption is FZS1000.
- FZS600 requires special care. Identify your exact model with the help of this document:
Installation Instructions. Especially older model years come with
significant restrictions and require additional effort.
- Your shipping destination and exact address (incl. c/o) and shipping options.
- Shipping only inside EU, origin is Germany.
- By default as "packet w/ tracking", others on explicit request.
- Shipping costs examples from DHL (as of mid of 2023):
| Destination | w/o tracking | w/ tracking | Customs duties |
|---|---|---|---|
| Germany | 4,00€ | 5,50€ | no |
| EU | 6,50€ | 15,00€ | no |
